pi coin?

Been some time since I've posted. good to see some oldies are still around here. Just wanted to drop by and ask around. with all the craze with cryptocurrency lately has anyone tried pi coin? I just started it and it looks legit so far, not worth anything at the moment but they said that about bitcoin years ago too haha. Basically download the app then you mine crypto from your phone. Its still in beta but you can use my name as an invite to try it out (detale). Their site https://www.picoin.biz/ Thoughts/opinions?
